HENRY LEFORT, OF NEWARK, NEW JERSEY.

ART OF FORMING PE NDA NTS FOR WATCHES.

SPECIFICATION forming part of Letters Patent No. 372,158, dated October25, 1887.

Application filed April '4, 1887.

IO my-invention appertains to make and use the same, reference being hadto the accompanying drawings, forming part of this specification.

In the formation of pendants for stem-winding watches it is necessarythat they be made tubular or hollow, so as to receive the pushpin, andalso that they be provided with openings to receive the ring of thewatch. The openings which receive the ring are made upon opposite sidesof the pendant; and, in order to properly finish such portions of thependant,

ears or lugs are usually soldered upon the out ,side of the pendant, andthrough which such openings also extend. In making such a pendant it hasheretofore been customary to take a single tubular piece of metal andfinish the same inside and out by grinding or boring until the desiredform and polish have been given to it, and to then solder the ears orlugs, before referred to, thereon,when the holes for receiving 3c thewatch-ring are bored through thesame.

The several operations required, when such method is followed, arenecessarily expensive,

because of the amount of labor required and the filings of the extramaterial required in such 5 a case.

The object of my invention .is to cheapen the cost of manufacturingpendants by forming and finishing-the same with as little material andlabor as possible; and to this end the 0 invention consists in making apendant of two parts, which are stamped from blanks and brought intoshapes adapted to be united together by soldering,while at the same timethe ears for the watch-ring are stamped out of the same piece of metal,as hereinafter more fully described and claimed.

In the drawings, Figure 1 is a front elevation of a pendant when thecrown is placed thereon and its other connections are made; and

ted lines, and, by similar lines, a portion of the watch-case. Fig. 2 isa plan view of the same pendant and ring of the watch when looking frombelow. Fig. 3 shows a blank formed of metal of suitable shape, to bestamped or drawn up so as to form one-half of the pendant, and Fig. 4 isa cross-section of the same, taken on the line 00 00 of Fig. 3. Fig. 5is a side elevation of one-half of the pendant after being drawn up orstamped from the blank shown by Figs. 3 and 4:, when looking at theoutside or back thereof, while Fig. 6 is a similar view of the reverseor inside of such half. Fig. 7 shows the two portions ready to be joinedtogether, the right-hand part, however, being shown in section, asindicated by the line 3 y of Fig. 8, which latter figure is an end viewof the two hal ves ready to be united together.

In the drawings, A represents the crown and B the pendant, while 0indicates the watch-- ring.

In order to form the pendant, a blank piece of metal, D, of the requiredshapeas, for example, that shown in Fig. 3-is taken, and by means ofsuitable dies the same is drawn or brought up into the form of a half ofthe pendant, as shown by Figs. 5 and 6. The same die may be made tostamp the cars a a upon such halves, or these ears may be formed byanother stroke or operation with a separate die. When the metal isthus-shaped, the finishing is very easily accomplished owing to Afterthe finishing, which in such case is slight, the two correspondinghalves of the pendant are placed in their relative position to eachother, the edges thereof being brought together or soldered, and thependant is then practically complete. If the holes for receiving thering are not already finished, this may be done after unitingthe twohalvestogether; but, asthe ears are already formed and are integral withthe other portion, the work required in completing the pendant, so as toreceive the ring, is very much less than when the ears have to besoldered thereon. In fact, the whole work of manufacturing pendants inthis manner is very much less, and at the same time more expeditious,than when made in the old way.

- 50 this figure shows the ring of the watch by dot-I Having thusdescribed my invention, what I claim as new, and desire to secure byLetters then uniting the parts,and finishing the same, Patent,issubstantially as and for the purpose set forth.
